PORCELAIN WATER GLOSET BOWL. No. 320,990.

UNITED STATES RICHARD HARTMAN WATSON, OF PHILADELPHIA, PENNSYLVANIA.

PORCELAIN WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 320,990, dated June 30,1885.

Application filed April 17, 18H54 (No model.)

To all whom t may concern:

Be it known that I, RICHARD HARTMAN VVA'rsoN, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented a new and useful Improvement inOne- Piece Porcelain Water-Closets, of which the following is aspecification, reference being had to the accompanying drawings, inwhich- Figure 1 is a vertical transverse section, with slightperspective touches. Fig. 2 is a transverse sect-ion at right angleswith Fig. 1, and taken at two altitudes, the right-hand portion on theline x fr, and the left-hand portion on the line y y, of Fig. 1.

It will readily be understood that the whole top of the closet is trueand level all around at one height, and the front and right and leftsides are alike, and that the back is entirely smooth and free from anyinwardlyoverhangi ng rim, and is convenient for cleanly wiping when itneeds it.

The same letters indicate the same part in each view.

A is the bowl; B and C, outlet water-way from the bowl to the soil-pipe;Dhthe inlet water-way to the wash.

E is a tubular extension of the saine to both the right and the left1upon one level, to the front of the closet, where the two streams meetagain at the center c, and are both turned into the perforated passageF, which extends across the front and to both the right and left sidesof the'closet, as shown on the right side in both Figs. 1 and 2.

G indicates what is called a fan77 or spreader It is a smooth thinporcelain H shows the curved inside corners, which are all alike, anddiffer decidedly from the outside angle of the bowl, as seen in Fig. 2.I obtain this contrast of inside and outside angles, as shown, by' meansof a hollow wall.

I shows an air-space in the hollow in that part of the wall of thecloset. This hollow diminishes down the side of the bowl and terminatessmoothly in contour of the closet, so as to give no outward or inwardindication how the difference in inside and outside angles in such amarked degree is accomplished. By this means the bowl is strengthened,and the inside is better tted or shaped for the wash, and the outsidefor the wood-work where it is to be placed.

J J are right and left ventilatingilues.

K K indicate openings downwardly into the bowl. Y

L L are pipe-[langes for ventilaiingpipe.

M indicates a porcelain lip extending down into the closet, so as toprevent water and paper from getting in'to the ail'passages from thecloset to the Ventilating-pipes. I have found this to be an importantmatter, as the draft inthe Ventilating-pipe favors its own obstruction.M effectually guards the ventilating-flues.

Having thus fully described my improvements in a square-topped one-pieceporcelain watercloset, what I claim as my invention, and desire tosecure by Letters Patent, is-

A porcelain water-closet bowl constructed with double Walls in whole orin part, with air-spaces between them, whereby lightness is preserved,while the internal and external shapes are varied at pleasure,substantially as and for the purpose herein set forth.

RICHARD HARTMANNVATSON.
